Installation must include an equipment shutoff
valve, union, and plugged 1/8" NPT tap. Lo-
cate NPT tap within reach for test gauge hook
up. NPT tap must be upstream from burner
system (see Figure 29).
Check your building codes for any special
requirements for locating equipment shutoff
valve to stoves.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could
result in clogged burner system valves.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
We recommend that you install a sediment
trap/drip leg in supply line as shown in Figure
29. Locate sediment trap/drip leg where it is
within reach for cleaning. Install in piping system
between fuel supply and burner system. Locate
sediment trap/drip leg where trapped matter is
not likely to freeze. A sediment trap traps mois
-
ture and contaminants. This keeps them from
going into burner system gas controls. If sedi-
ment trap/drip leg is not installed or is installed
wrong, burner system may not run properly.

plied with the appliance or you can purchase
it from your dealer.

Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• sealant (resistant to propane/LP gas, not
provided)
1. Open lower door panel.
2. Route flexible gas line (provided by install
-
er) from equipment shutoff valve to burner
system (see Figure 30). Route flexible gas
supply line and attach to valve.
3. Check all gas connections for leaks. See

CHECKING GAS CONNECTIONS
WARNING: Test all gas piping
and connections, internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an
open flame to check for a leak.
Apply noncorrosive leak test so
-
lution to all gas joints. Bubbles
forming show a leak. Correct all
leaks at once.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect appliance with its appliance
main gas valve (control valve) and equip-
ment shutoff valve from gas supply piping
systems. Pressures in excess of 1/2 psig
(3.5 kPa) will damage burner system gas
regulator.
